Your creature is gone, but hey, at least you gained some life
Depending on how youve built the deck, you might also get mileage out of: Jarad, Golgari Lich Lord & Bonehoard combo Birthing Pod, Jarads Orders, and Pattern of Rebirth for creature tutoring Force of Vigor as a way to interact without taking a turn off to transmute Agent of Erebos to remove opposing graveyards Solemn Simulacrum or Disciple of Bolas for sheer consistency The opportunities to use this package for your strategy are near limitless, and whilst I think the card is a slamdunk in Meren, its also great in Orzhov aristocrats decks, and probably in other builds like Grixis Spellslinger too
Tolaria West, Muddle the Mixture, and Dimir House Guard tend to be some of the more common transmute cards
Thats true of most of the cycle, but this one doesnt affect the game state at all, and the set has little else to support a mill engine
